Intel has been publishing research for about a decade on what they call “3D Trigate” transistors, which held out the hope for both improved performance as well as power efficiency. Today Intel revealed details of its commercialization of this research in its upcoming 22 nm process as well as demonstrating actual systems based on 22 nm CPU parts.

The new products, under the internal name of “Ivy Bridge”, are the process shrink of the recently announced Sandy Bridge architecture in the next “Tock” cycle of the famous Intel “Tick-Tock” design methodology, where the “Tick” is a new optimized architecture and the “Tock” is the shrinking of this architecture onto then next generation semiconductor process.

What makes these Trigate transistors so innovative is the fact that they change the fundamental geometry of the semiconductors from a basically flat “planar” design to one with more vertical structure, earning them the description of “3D”. For users the concepts are simpler to understand – this new transistor design, which will become the standard across all of Intel’s products moving forward, delivers some fundamental benefits to CPUs implemented with them:

Leakage current is reduced to near zero, resulting in very efficient operation for system in an idle state.

Power consumption at equivalent performance is reduced by approximately 50% from Sandy Bridge’s already improved results with its 32 nm process.
